Clogging at Pore Scale and Pressure Induced Erosion
Robin Jäger, Miller Mendoza, Hans J. Herrmann
Introducing a model to study deposition and erosion of single particles at microscopic scale, we investigate the clogging and erosive processes in a pore. The particle diameter, co…
The Mechanism behind Erosive Bursts in Porous Media
Robin Jäger, Miller Mendoza, Hans J. Herrmann
Erosion and deposition during flow through porous media can lead to large erosive bursts that manifest as jumps in permeability and pressure loss. Here we reveal that the cause of…
Fully dissipative relativistic lattice Boltzmann method in two dimensions
Rodrigo C. V. Coelho, Miller Mendoza, Mauro M. Doria +1
In this paper, we develop and characterize the fully dissipative Lattice Boltzmann method for ultra-relativistic fluids in two dimensions using three equilibrium distribution funct…
Critical bursts in filtration
Filippo Bianchi, Marcel Thielmann, Lucilla de Arcangelis +1
Particle detachment bursts during the flow of suspensions through porous media are a phenomenon that can severely affect the efficiency of deep bed filters. Despite the relevance i…
Channelization in Porous Media driven by Erosion and Deposition
Robin Jäger, Miller Mendoza, Hans Jürgen Herrmann
We develop and validate a new model to study simultaneous erosion and deposition in three-dimensional porous media. We study the changes of the porous structure induced by the depo…
Dean Instability in Double-Curved Channels
J. -D. Debus, M. Mendoza, H. J. Herrmann
We study the Dean instability in curved channels using the lattice Boltzmann model for generalized metrics. For this purpose, we first improve and validate the method by measuring…
Superdiffusion of massive particles induced by multi-scale velocity fields
Reza M. Baram, Pedro G. Lind, José S. Andrade +1
We study drag-induced diffusion of massive particles in scale-free velocity fields, where superdiffusive behavior emerges due to the scale-free size distribution of the vortices of…
Numerical Simulation of Particle Flow in a Sand Trap
A. D. Araújo, J. S. Andrade, L. P. Maia +1
Sand traps are used to measure Aeolian flux. Since they modify the surrounding wind velocity field their gauging represents an important challenge. We use numerical simulations und…
Lattice Boltzmann simulations of apparent slip in hydrophobic microchannels
Jens Harting, Christian Kunert, Hans J. Herrmann
Various experiments have found a boundary slip in hydrophobic microchannel flows, but a consistent understanding of the results is still lacking. While Molecular Dynamics (MD) simu…
